REI Co-op Helix Insulated Air Sleeping Pad

Light, plush and warm—what's not to love about this REI Co-op insulated pad? It's 3 in. thick for comfort in any sleeping position. A 4.9 R-value means it provides a warm night's sleep in any season.

Interior baffle design and weld shape reduce internal stresses, improving pad durability and longevity. Two layers of reflective insulation create a very light pad with amazing insulation properties, while the even, gridded weld pattern evokes mattresslike flatness and comfort. Separate, color-coded valves for inflation and deflation make setup and breakdown frustration-free and work seamlessly with the included pump sack.
